As a direct consequence, most sections don't have any fixed order. Therefore, this article will only document the data structures and mention the order Nintendo places sections in. For more details, it is recommended to look at the [https://github.com/leoetlino/evfl <code>evfl</code> library] directly. | As a direct consequence, most sections don't have any fixed order.

Another consequence is that sections must be aligned to 8-byte boundaries in most cases to avoid unaligned memory accesses (this is not as important for strings). | |||
